            Bug ID: 441135
           Summary: System tray causes system to crash
           Product: kde
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org

  Target Milestone: ---

SUMMARY
This has happened to me quite a few times now, and it is a pretty bad bug since
it freezes my system.

I am not 100 % confident that the system tray causes the issue, but it seems
like it does. So what happens?

Sometimes, when I hover/click on something in the systray, KDE starts horribly
lagging and after a few seconds, freezes completely. The only thing moving and
working is the mouse cursor. I have attached a system journal log which
contains errors with timestamps approximately when KDE froze. Somehow, it
recovered.


STEPS TO REPRODUCE
UNKNOWN

OBSERVED RESULT
KDE freezes completely.
